The four ninjutsu obtained through the exchange, the technique of the earth rock needle, the technique of soil diversion, and the technique of mud clone, and the technique of earth ball bullets.

The earth rock needle is a C-level ninjutsu, the function is similar to the rock long gun, it is obviously a variant of the earth dragon gun, with a considerable number of earth rock needles made by the earth escape, after the ninjutsu is launched, the rock needles that rise from the ground shoot indiscriminately, and the coverage area is quite large.

"Earth Rock Needle Technique!" The flying needles fluttered around, and it looked quite spectacular. However, when the dust settled, Uehara saw the shortcomings of this technique, and the rock needles shot at the trees, some of them were broken, some of them just pierced the bark and fell to the ground, and some of them hung on the leaves.

"I haven't seen this technique in our time. It is estimated that it is a technique developed by a middle ninja. Seeing Uehara's failed ninjutsu experiment, Tuya said noncommittally.

"Twelve seals, right? The order is...... Ninja - the art of the earth rock needle! "Different people use the same technique to produce completely different results. The smoke cleared, and a small area of the vicinity was covered with broken branches and leaves as if it had been strafed by machine guns. Uehara walked closer to check, and the black and faint rock needle was nailed into the trunk of the tree without breaking, which was enough for a C-level ninjutsu.

"Awesome! How? Uehara couldn't wait to ask, the fat man and Xuelesa next to him, and a group of people from the first class of the ghost Oishi class were all eager.

"Tell me about your understanding of Chakra." Looking at the people besieging the city, Tuya was in a rare mood to teach them.

"Chakra's words, a kind of energy ......formed by the perfect combination of mental energy and physical energy," Uehara replied with some uncertainty, he had not received special ninja training, and the only ninjutsu knowledge he knew was also obtained by reading manga in his previous life.

"Yes, that's right, you should have learned all of this in school. And what I'm going to talk about next is the chakra nature and morphological changes. Tuya sat up straight, his expression becoming serious.

"The five attributes of wind, fire, water, earth, and thunder are chakras, and the changes in the nature of soil attributes are the easiest to grasp, and you have probably discovered it, if you concentrate your efforts and control them with all your strength, the chakra that is compressed to an extremely rich point is basically the texture of the rock." Tuya said, the earthy yellow chakra slowly condensed in his hand, gradually condensed into an entity, he threw it casually, and hit the tree with a bang, listening to the sound, it was clearly the sound of stones hitting the trunk.

"The amount of chakra is very important, but the quality is equally important, the characteristics of the soil attribute are thick and tough, after mastering the attribute change, the high-quality chakra is integrated into the earth, and a small amount of chakra will greatly change the soil quality of the earth, although the earth escape ninja is the least affected by the environment, but if there is a suitable terrain, there is a lot of improvement in the earth escape ninjutsu." Tuya looked at Uehara, who was frowning and thinking: "Uehara, you should be the most aware of the importance of forming, if you are on the ground full of rocks, the power of the earth rock needle will be doubled. ”

"As for the other nature change, it is something that you will have to master when you become a ninja, develop the second attribute chakra, the most common second attribute of the earth ninja is water. Also, the change in the form of chakra, if you want to be promoted to the upper ninja, you also need to master it......"

——

This half-hour-long conversation undoubtedly opened a window for Uehara to spy on a higher level of power.

"Chakra's nature has changed, but unfortunately, I didn't understand." Uehara thought helplessly in his heart. Knowing that this is the knowledge that must be understood to become a high-level ninja, he can understand the meaning of every word and sentence that Tuya said, but when combined, it makes Uehara in the clouds. However, looking at the fat man, Xuelesa and the people in the ghost head Oishi class looked thoughtful, Uehara had no choice but to smile bitterly, the problem was still exposed, and he only accepted the current body and the instinct of ninjutsu, and he didn't know anything about the theoretical knowledge of ninjutsu. No one would have guessed that Uehara, who seems to be scheming on the outside, is completely illiterate on the inside.

"Fatty, Shelersha, let's keep practicing!" If you can't figure it out, you won't want to think about it for the time being, so Uehara beckons to his companions and first grasps the power that he can master.

"Ninja - the art of earth pill bullets!" The principle of this technique is simple, using a lot of fist-sized clods made by chakra, launched like kunai, the clods are not large enough, and the power is naturally lacking, but this technique is extremely fast, with only six handprints, if it is used as a means of emergency defense or interference, it is likely to be of some use.

The technique of earth diversion and the technique of mud clone were exchanged by Xue Lesha from a ninja with dual attributes of water and soil, and the three of them in Uehara were all single earth attribute chakra, so they had no way to practice, so they had to be put away as a reserve ninjutsu.

——

"Everyone is very diligent, and they are still practicing." The tooth that disappeared for a while came back at some point.

"Our combination ninjutsu, Earth Tooth, do you want to try it!" Uehara was eager to try.

"Well, since you have faith, come on." Tuya took a step back and spread his hands indifferently.

"Then be careful, we're going to go!"

"Earth Escape - Earth Rock Needle Technique!"

"Earth Escape - The Art of Earth Pills!" Uehara and Shilesa launch ninjutsu one after the other.

"Earth Escape - The Art of Uniting the Earth Flow Wall!" Ninjutsu support from the first class of the ghost has also arrived.

"Tu Dun - Tuling Tuanzi's Technique!" The fat man and the big stone class were the last killer moves, and the four grinding discs-sized clods flew towards the earth teeth.

"It's good, it's troublesome." Tuya looked at the whistling clods of dirt and didn't dodge.

The first joint operation of the three squads, Uehara's plan was that the earth rock needle disrupted the movement of the earth tooth, so that he did not have time to seal the counterattack, and when he jumped up, the earth pellet bullet of Xuele Sha suppressed him on the ground again, and then the joint earth flow wall of the ghost first class limited the range of movement of the earth tooth, and the last four people gathered to use the earth ling, which will launch a fatal blow.

"Yes, Ao." When the smoke and dust cleared and Tuya's figure was nowhere to be seen, Uehara was about to remind everyone of the next battle plan, when Tuya's voice suddenly sounded in his ears.

"It's so easy to lose, huh? Is it an instantaneous technique? Uehara was frustrated.

"The number of rock needles in Uehara has been reduced, and the chakra saved is used to strengthen the strength of the rock needles, so the power has been greatly improved, which is a good idea. However, without mastering the changes in the nature of chakra, it is impossible for a person's thinking ability to inject chakra into multiple needles at the same time. Tuya patted Uehara on the shoulder and commented on Uehara's shortcomings.

"Xue Lesha's earthenball projectile, the attack power is too weak, as a harassment and suppression force is not enough, this level of attack power, you don't even need to dodge, you can ignore it by directly protecting the vital points of the body. The solution is to either divide the pellets into smaller and more dense enough to disrupt the enemy's line of sight, or reduce the number of pellets and strengthen them with saved chakras, at least to maintain the minimum effective lethality. After commenting on the technique of earth pill bullets, Tuya looked at the ghost head class again.

"It's good to use the Earth Flow Wall as a means of restricting enemy ninjas, and it can be used in many situations, and it is very universal. This idea clearly has the characteristics of the Kamihara class, but it also has obvious drawbacks. The disadvantage is that the range of the Earthflow Wall can be limited is not large, and as the distance increases, the consumption of chakra and the time to activate ninjutsu will increase, and it is almost impossible to activate the Earthflow Wall quickly enough behind the enemy without being dodged. Regarding the idea that the advantages and disadvantages of the ghost first class are equally prominent, Tuya said again: "There are a lot of bondage ninjutsu in Tu Dun, you will come into contact with it in the future, and the effect will be much better if you replace Tuliubi with bondage ninjutsu." ”

"As for your last group of attacks, concentrate the Tuling regiment and use it, in fact, this is the usual tactical means used by our Iwa Shinobi in large-scale operations. Theoretically speaking, if a hundred middle ninjas launch the Tuling danzi together, even the upper ninja will not be able to completely dodge, and it is even likely to die as a result. Tuya was very pleased with the idea, and he spoke again, "If just now, if it wasn't just the four of you who used Tuling Dango together, but nine people together, then I probably wouldn't have had the space to use the Instantaneous Technique, and the battle wouldn't have ended so soon." ”

After a long pause, after seriously commenting on all the ninjas in the reconnaissance and vigilance squad, Tuya took out a scroll and threw it in his hand, "After the technique of the earth flow wall was handed over to each class, it has now become the core ninjutsu of the current class operations, which is very good, indicating that each class is skilled enough in the use of the art of the earth flow wall, so it is necessary to carry out the second technique." B-level ninjutsu, ripping the earth and turning the palm, a powerful and not low-level technique. ”

"In addition to the reconnaissance and vigilance class, have other classes also started the cultivation of this technique? Captain Tuya. Uehara asked.

"Not yet, the reconnaissance alert squad is most likely to be the first to contact actual combat, so it has become necessary to enhance your attack ability, as for other classes, if Tuliubi is the core ninjutsu of Tu Dun defensive ninjutsu, then ripping earth and turning palm is the core of offensive ninjutsu, and this technique is a compulsory ninjutsu for all classes." Tuya opening explained.

His gaze swept over the nine ninjas in the three classes, and finally, Tuya threw the scroll to Uehara, "The reconnaissance class and the defense class are no longer on the same level as the ordinary class and the elite class, we will come according to our own plan." Uehara, I'll leave the training of the three classes to you. "Don't wait for Uehara to refuse, I can't see the people of Tuya anymore.

"Then everyone ......"

"It's all up to you, Uehara, the first class of the ghost obeys your arrangement."

"The same goes for the Oishi class."
